After some research I found an oil filter that will fit a 68 b body with a 6.4L hemi swap and the 45 degree adaptor. The Fram filter is PH10060 and the Mopar part number is: 4892339AA. The Mopar number came direct from Mopar and the Fram is the cross reference number. The filter is smaller than I would have liked but it works.
